Take a look at this presentation by Seth Godin. I love the part where he talks about companies slapping a warning label on dangerous products instead of fixing the product itself.

Seth Godin spotted this blog post on specialization. If you have a law firm web site or blog, you should take his advice to heart. While for a large law firm, the breadth of practice areas may demonstrate size and strength, for a solo or smaller practice, someone that visits your web site or blog may think you are spreading yourself too thin. Can anyone really be a specialist in 3 or 4 practice areas? You want to project to a potential client that you really are a master of divorces of he is seeking a divorce, or a master of copyright if he has a copyright issue.
